Filed: 1953-02-13
Abstract: 724,414. Photographic type-composing. MONOTYPE CORPORATION, Ltd. Feb. 13, 1953, No. 4057/53. Class 98 (1). [Also in Group XVI] In a positioning mechanism for a character-bearing plate movable in two directions to position a desired character relatively to a lens in a photographic type-composing machine comprising a pair of oppositely movable positioning levers each furnished with a jaw co-operating with a stepped series of movable gauges each of which can be projected selectively into the path of the jaws, there is provided loosely mounted on and in advance of one of the jaws a supplementary jaw, and mechanism for moving the supplementary jaw into and out of operative position relatively to the gauges. Mounted pivotally on one of the primary jaws A<SP>3</SP>, Figs. 4, 5 and 8, of the matrix-case positioning mechanism is a supplementary jaw C having three pin-engaging recesses C<SP>1</SP>, the jaw C being pivoted by means of a rib C<SP>2</SP> projecting into a channel in a hood a in the jaw A<SP>3</SP>. The jaw C is in advance of the jaw A<SP>3</SP>, and is normally in a position to engage a projected gauge pin A. When air is admitted to a cylinder D<SP>3</SP> in response to a perforation in the record strip, a piston D<SP>2</SP> is raised and rocks a bar D to raise the jaw C into inoperative position, a spring D<SP>4</SP> returning it when the air supply is interrupted. Thus some or all of the pins may each position the matrix-case in one of two alternative positions, according as the jaw C is raised or lowered, whereby matrix-cases having more than fifteen columns may be controlled by fifteen gauge pins. If a fifteen-column matrix-case is used, a frame G<SP>4</SP> is manually moved to the right in Fig. 8, causing a wedge piece E to engage a lug D<SP>5</SP> on the bar D and lock the jaw C in its lower position, and also causing a sliding bar F<SP>1</SP> to act on a pin F and move it into position to block a rod attached to the matrix-case, so as to avoid over-travel of the latter. A large matrix-case has a nose arranged to pass under the frame G<SP>4</SP>, but the nose of a small case is arranged to abut the frame and move it to the right if the operator has neglected to do so. Specifications 8633/99, [Class 100], and 563,331 are referred to.

Title: Numerical data processing systems
IPC: G06F9/46
Filed: 1972-02-01
Abstract: 1373720 Data processing COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 1 Feb 1972 [2 Feb 1971] 4722/72 Heading G4A In a data processing system including a plurality of processors U1-Un and a common zone-organized data store M of the type in which data is destructively read out in a first half cycle and reinstated in a second half cycle, the half cycles of exchange requests from at least two distinct processors may be interleaved, a check being made at each request to ascertain whether the zone which a processor desires to access has been previously accessed, the processor request being satisfied only if the addressed zone has not been previously read out. During the first half cycle of a request from a processor, gate G 0  is enabled at a time t 0  so that the address code of the requested zone S 0  ...S m  of store M is entered into register RA, bi-stable B being simultaneously set to its "zero" state. The contents of a zone address register s i  associated with the requested zone S i  are read into a read/write register R and if they correspond to a code indicating that the zone has been previously accessed gate G 1  is enabled and, at time t 1 , bi-stable B is set to its "1" state by gate G2 so that a signal is set via interface IL to the processor to indicate that its request cannot be satisfied since the requested zone has been destructively read out. If register R does not contain such a code the calling processor is informed that its request is satisfied and before the end of the first half cycle the code is read into the address register of the accessed zone. This code may be permanently stored in a register C 0  or, if the zone address registers are also of the destructive read out type the code may be chosen to be all zeroes in which case the required code is automatically obtained by read out of the register. During the second half cycle the codes are cleared from the previously accessed zone address registers and their address code reentered. This is effected by, in each second half cycle, enabling gate G7 at a time t 1  so that the address code in register RA is entered into read/ write register R. The contents of the register R are then read into the appropriate zone address register s i  at time t 2 .
